TI LMV791MKX/NOPB

The LMV791 (single-channel) and LMV792 (dual-channel) low-noise CMOS input op amps offer a low input voltage noise density of 5.8nV/√Hz with a quiescent current of only 1.15mA (LMV791). The LMV791 and LMV792 are unity-gain stable op amps with a 17MHz gain bandwidth. The LMV79x features a supply voltage range of 1.8V to 5.5V and can operate from a single supply. All LMV79x devices feature a rail-to-rail output stage capable of driving 600Ω loads with source currents up to 60mA. The LMV79x series delivers excellent performance in low-voltage, low-noise systems. The CMOS input stage offers a typical input bias current of only a few femtoamps, and the input common-mode voltage range includes ground, making the LMV791 and LMV792 ideal for low-power sensor applications. The LMV79x series features a built-in enable function for optimizing power consumption in low-power applications.
